2009 Volkswagen Jetta: misfire or rough idle

Filed Mar 23, 2017 · Engine · 73,000 miles · CA

First my car had trouble turning over after a misfire. Then while driving the car (in motion) as I was coming to a stop the engine began to sputter and feel as if it was lunging forward. I drove it straight to the vw service center which was nearby. Now they are telling me it is a timing issue which I suspect to be the timing chain tensioner.

This car is a vw jetta tdi (turbodiesel). Driving on I-96 between lansing and brighton the jetta began to run roughly with a loss of power. The traffic was very slow due to a snowstorm, so I was able to continue driving. The car ran increasingly rough and eventually stopped. The car was towed to my local dealership, germain vw in ann arbor. The report was fuel system failure due to the hpfp breaking apart. The entire fuel system will need to be replaced and the fuel tank fully cleaned of metal fragments.

Car has stuttered when accelerating from stop since purchasing with 12 miles. On 12/21/2009, car lost power and stuttered at speed on interstate highway. The road immediately climbed a hill. With accelerator to the floor, the car dropped to under 60 MPH and I shifted from 6th to 5th. Car still kept decelerating so I shifted to 4th. Fortune provided a rest area as the car got to about 45 MPH on the interstate. After parking, car stalled while idling. Starting engine would roughly idle at 1/2 of the idle RPM for about 5 seconds before stalling. After 4 tries, I let the car sit for 10 minutes and it restarted without further incident. The car had diesel purchased in upstate ny in the winter, presumably a winter blend. The incident happened in va in 30+ degree temperatures, so presumably gelling of the fuel was not the problem. Additionally, on 12/17/2010, car started but would not rev above 1500 RPM even while out of gear. Would not go more than 10 MPH. I assume it is the fuel system but the vw dealer claims everything is fine with the car.

2009 vw tdi jetta. Engine runs rough, sutters at certain points and lacks power. Will sometimes stall in traffic. Have documented with dealers. Vw america refuses to answer. Vw has software fix, but will not apply it to vehicle. Do people have to be killed before these people pay attention.

During the cold winter months in nh. My 2009 vw jetta sportwagen tdi has exhibited a engine stumble problem when it is started. The car will start but run rough and abruptly stall. It takes on average of 5 starts before the engine will stay running in a smooth manner. Most of the events have been after driving more than 30 miles and parking it overnight in a non-heated garage at 44f. One occurrence was in my work parking lot after sitting 8hrs in 30f weather. This problem has occurred a total of 10 times. The problem occurs about once a week. Most recently it started and didn't run rough until I had pulled out on to the road. The engine started to run rough and I had to pull off to the side. The car had to be shutoff and restarted before it ran smooth. The outside temperature was 10f. The car has been to vw service twice. The car doesn't trigger a code for vw to diagnose, but the problem is very real. Vw doesn't know what is wrong and no repairs have been made. The car could leave my family stranded in cold conditions or possibly hit while the car is on the side of the road.
